The Perimeter Community Improvement Districts is rallying support for reconstruction of the I-285-Ga. 400 interchange, getting local governments to endorse the project.

The interchange was among the largest on a proposed list of transportation upgrades that would have been funded by a penny sales tax. Voters shot down the tax on July 31, but Gov. Nathan Deal’s administration says the project is a top priority.

The Sandy Springs City Council on Oct. 2 approved a resolution expressing its support, following a similar resolution passed by the Perimeter CID board.

Perimeter CID President and CEO Yvonne Williams said the city councils of Dunwoody and Chamblee will soon consider a similar show of solidarity.

“It’s our effort to always be united and focused,” Williams said.

She said reconstruction of the interchange was among the more popular on the list that residents rejected.

Williams said she is confident that Deal will complete it. The estimated price tag is $450 million.

Williams said the Perimeter CID and their partners are making sure Deal understands how important the project is to the region.

“We never let up,” Williams said. “The status quo doesn’t work for our agenda.”

The resolution passed by the Sandy Springs City Council calls the interchange “a top priority of regional significance” and commits to the creation “of the cross-jurisdictional public/private ‘top-end’ Perimeter collaborative” to support the project.
